NETWORK TOPOLOGY
The
way computers are physically connected is very important in computer
networking. How the computers are physically to one another is called Network Topology.
Computer
networking can be done in various way and some of the main ways are given
below.
Star
Topology
The
computers are connected here in the shape of a star.
A
computer or a hub or switch is used here in the middle to connect all the
computers to one another.
It
is very easy to install a star network and it is relatively easy to identify
and correct errors there. The main disadvantage of this network are the
necessity to use a lager number of wires to connect computers to one another
and the fast that if the computer, hub or switch in the middle breaks down, the
whole system will be broken.
Ring/Loop Topology
This network is arranged connecting
computers to one another in the form of a ring or loop. Even though the need of
a few wires to connect computers can be mentioned as an advantage, the main
disadvantage in a ring network is that if one computer does not operate, the
whole network will collapse.
Bus
Topology
This computer network is built cantering on
a main wire and connecting all the computers and other devices to it. The
advantages of this are the need of a few wires and the convenience to fix
computers and other devices. A main disadvantage of this is the fast that the
whole network depends on the main wire. Further, closing the main wire at both
ends using terminators is a difficult task.
· Tree Topology
Tree topology takes shape of separated
branches of a tree. One advantage of this Kind of a network is the possibility
to control each branch separately. However, building and controlling this
network can be a bit-complicating task. Further, a main wire as in bus topology
is used here to connect the branches of this network and the function of the
network depends on it.
